Problema di colori tra nef e tiff

Salve, ho fatto ormai tantissime prove, in ogni modo da me conosciuto per provare a risolvere il seguente problema senza mai trovare soluzione.

Ogni file Nef ( ho provato anche con raw canon) una volta elaborato e sviluppato quando clicco su modifica con (in questo caso photoshop) e trasformato in tiff, i colori cambiano, non lo fa con tutte le foto, o meglio non è un cambiamento visibile in tutte le foto, ma si verifica un leggero cambiamento dei toni, un altro problema sarebbe l'applicare la grana su nef ed una volta trasformato in tiff la foto risulta diversa dall'anteprima, con una grana diversa ed una perdita di contrasto e saturazione nel tiff che nell'anteprima raw di c1 non risulta, credo sia un problema di anteprima.

Ho provato cambiando la dimensione delle anteprime (ora e normalmente in 2560px fino a la risuluzione più bassa) ed il problema non si risolve, sono sicuro non dipende dai profili colore poichè anche con prova attivata questo si verifica, ho provato a disabilitare la gpu e comunque il problema persiste, credo siano 2 problemi correlati alle anteprime.

grazie mille a chi saprà aiutarmi.

  In my opinion, it's not a problem of preview size but rather a problem of colour spaces/profiles.

  Which colour profile/space do you use when working with Capture One ? You can have a look at the profile you use by looking at View -> Proof Profile. If the proof profile is given as "selected recipe", have a look at the recipe you use. And this profile should be the same as the one defined in the field "ICC profile" of the window which is created when you click on "Edit with...". All the colour spaces/profiles should be consistent if you want to have the same colour rendering.

  And be careful to use "Edit with..." and not "Open with....". Otherwise, your file will be opened using Adobe Camera Raw (for Photoshop), which will give you a completely different rendering and suppress all the adjustments you've done.

  Hi robert, so thanks but of course i use only "edit with" and not "opern with", the color profile that i use for open is srgb, and of course i use "try color" for see the preview in the correct profile that is srgb, beacouse i need this in the end and my display is precise with srgb.

  in the end: is not my foult, is c1 to give this problem, apparently without reason.

  i have try with so much type of different raw, but the problem is not fixed.

  all tipe of action that i need to do for not have problem i have use, but nothing.

  of course other software are totaly different, i hope to have explain good, the problem is that the preview of c1 is different than the tiff file that i go to use. and is not problem of color space. only c1 don't give a correct preview.

  another but similar problem is that i do grain at photo (silver for exemple) at maximum level the preview is totaly different that the file than i have in the end, if i export in jpg or "edit with" for have a tiff not change, the photo in the end is low level saturation e low contrast than preview that i have in c1, i think is a cache problem.

  Sorry, as I don't have this issue (my previews in C1 are strictly identical with the TIFF in Photoshop in my colour space, ProPhoto), I can't help you any further.
